While I redo my front suspension, I'm cleaning the frame for refinishing - just back to the doors for now. My car was undercoated & once removed i'm left with a (suprisingly) clean, bare steel frame. It's a driver & I'm not too concerned with originality or perfection. I want a satin finish, and I want to brush it on. The frame isn't 'sandblast' clean... no doubt there's some leftover undercoating in the crevices & hard to get to places, but it's pretty clean.
Since there's almost no rust, sticking to / sealing / converting rust is less important than sticking in general to an occasionally imperfect surface. And yes, I know how important surface prep is, and I'll do my best but there's a limit to what can be done with the car on the frame.
I feel like an undercoating product that stays flexible (like Rusfre & many others) would hold better than a paint-based product like Magnet Paint's Chassis Saver that could chip or flake off if not adhered properly. Any thoughts or opinions to share?
